I didn't argue against cherry picking (which I'm also against) I was arguing against the parent opposing something entirely different than the post he was responding to. I divided the implication into two.
The guns-to-deaths implication isn't clear cut either, but less so than the laws-to-guns one.
My argument is that this is mostly cultural, which is why it's so hard to measure. The reason being that gun culture both creates a cliate of many guns, but also the other way around (many guns means people are more likely to use/buy guns). Comparable societies (such as US vs rest of western world).
By "more guns" I include not just more guns sold/owned but "more guns in circulation" i.e. number of guns on streets, in cars, in bedside tables, as opposed to in gun safes.
A lot of countries with lots of guns have mostly locked up rifles and very few handguns. That blurs these statistics.
